Abstract
The invention discloses a PE filtering element production process, which comprises: adding ultrahigh molecular weight polyethylene powder serving as a filtering medium in a mold; placing the mold in a heating furnace for sintering; and taking the mold out, cooling the mold and removing the mold. The invention has the advantage that the production process is simple and easy to implement. The produced high-efficiency PE filtering element is very tough, acid and alkali resistant and insusceptible to break, and the filtering precision of the produced high-efficiency PE filtering element is 0.3 to 150 mu m. Because salt or alkali solid particles are added in the ultrahigh molecular weight polyethylene powder, the porosity is improved to 48 to 54 percent, and the pressure is 0.03 mu Pa. The production process is nontoxic, free from self-pollution, convenient for back flushing and recyclable.
Description
Technical field:
The invention belongs to a kind of preparation technology of filtering product, particularly a kind of production technology of PE filter element.
Background technology:
The present complex manufacturing of PE filter element, low, the acidproof alkaline error of the filtering accuracy of product, porosity be low, poisonous, can produce automatic pollution, be difficult for the not reproducible regeneration of blowback uses, and the cost of manufacture height.
Summary of the invention:
Purpose of the present invention just is to provide a kind of production technology of PE filter element, and this production technology is simple, and the filter element acid and alkali-resistance of producing, porosity height, nontoxic, no automatic pollution, easily blowback renewable repeated use.
Technical scheme of the present invention is: a kind of production technology of PE filter element, it is characterized in that: select that the ultra high molecular polyethylene powder is filter medium and adds salt or alkali between the 20-200 order for use, pack into then in the mould, put into the heating furnace sintering at last, taking-up, cooling, the demoulding get final product.
The weight proportion of above-mentioned salt or alkali is 1-60%.
Above-mentioned sintering temperature is between 180-300 ℃, and sintering time is between 10-150 minute.
Advantage of the present invention is: simple, the easy row of production technology.The high efficient PE filter element good toughness of producing, acid and alkali-resistance, difficult broken, filtering accuracy is 0.3-150 μ m.Owing to added salt or alkali solid particle at the ultra high molecular polyethylene powder, therefore increased porosity, be 48-54%, pressure will be 0.03 μ Pa.Nontoxic, no automatic pollution, easily blowback renewable repeated use.
The specific embodiment:
Embodiment 1: selecting 60-120 order ultra high molecular polyethylene powder for use is filter medium, and adds the 5%Nacl particle therein, in the stainless steel mould of the Φ 38X1500 that packs into then, put into the heating furnace sintering at last, temperature is controlled at 240 ℃, and sintering is after 90 minutes, and taking-up water-cooled, the demoulding get final product.Product is Φ 38X1500,5 μ mPE filter elements.
Embodiment 2: selecting 60-120 order ultra high molecular polyethylene powder for use is filter medium, and adds the 5%Nacl particle therein, in the stainless steel mould of the Φ 360X8 that packs into then, put into the heating furnace sintering at last, temperature is controlled at 250 ℃, and sintering is after 60 minutes, and taking-up water-cooled, the demoulding get final product.Product is the PE plate of Φ 360X8, and its porosity is 50%.
Claims (3)
1. the production technology of a PE filter element is characterized in that: select that the ultra high molecular polyethylene powder is filter medium and adds salt or alkali between the 20-200 order for use, in the mould of packing into then, put into the heating furnace sintering at last, taking-up, cooling, the demoulding get final product.
2. the production technology of high efficient PE filter element according to claim 1: the weight proportion of above-mentioned salt or alkali is 1-60%.
